WRENCH.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed September 6, 1912. Serial No. 718,963.

To all whom it may concern:

Be it known that I, DANIEL G. GAY, a citizen of the United States,residing at Summerville, in the county of Union, State of Oregon, haveinvented certain new and useful Improvements in Wrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same This invention has specialreference to wrenches and more particularly to a wrench having pivotedhandles with their jaws adapted to move in opposite directions relativeto the gripping portions of the handles and so disposed and connectedthat it is unnecessary to cross the same, whereby the weakening of thehandles at this point is rendered unnecessary.

Specifically, the invention consists in providing means in the form of aspring for drawing the free ends of the handle together, thereby causingseparation of the jaws, while a block or slide is mounted between thehandles and held from lateral displacement and adapted to be wedgedbetween the handles for positively gripping an article without exertingthe pressure of the hand. I

lVith the above and other objects in view, the invention consists ofcertain other combinations and arrangements of parts as will behereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which:

Figure 1 is a top plan view of my improved wrench, the same being shownin a position before engagement with an article.

Fig. 2 is a similar view but showing the device engaged with thearticle. Fig. 3 is an edge elevation of the device. Fig. 4 is a crosssectional view taken on the line H of Fig. 1. Fig. 5 is a sectional viewtaken 5 on the line 5-5 of Fig. 1. Fig. 6 is a detail yiew showing theband for connecting the aws. As illustrated, my improved wrench embodiesa pair of handles 10 which are ta- =9 pered in opposite directions toprovide enlargements 11 terminating in jaws 12. The

handles are pivotally connected for lateral movement one with relationto the other through the enlargements as shown at 13 and suchenlargements are inclosed by a strap or band 14 which incloses thebottom and side faces exteriorly of the jaws and receives the pivottherethrough to hold the jaws from displacement laterally beyond apredetermined point.

The inner faces of the jaws are provided with longitudinal grooves 15which receive a block or slide 16 which is of substantially circularform but provided with a tapered edge portion 17 for fitting the groovesand holding the same from displacement. The free extremities of thehandles are connected by a resilient element or retractile spring 18which holds the handles in positive contact with the block or slide 16and prevents displacement of the latter while at the same time spacingthe jaws apart.

hen it is desired to grip an article between the aws of the wrench, thehandles are moved on their pivot to separate the jaws assisted by theaction of the spring 18 so as to space the jaws apart and freely receivethe articles to be clamped therebetween. The block or slide 16 is thenforced along the grooves toward the pivotal connection of the handles soas to spread the latter and moves the jaws into binding contact with thearticle to be gripped between the jaws whereby the same may be handledwithout manually gripping the same.

From the foregoing description in connection with the accompanyingdrawings, it will be apparent that a wrench structure has been providedwhich greatly facilitates the use of the wrench, especially in view ofthe fact that the article is held in a gripping position and the fullleverage or use of the hand moving the same is permitted without thenecessity of exerting the pressure of the hand and fingers thereof forclamping the article.

The device embodies a simple combination of parts which will provestrong and durable and economical toproduce.

I claim:

1. A wrench comprising a pair of handles, said handles having convexenlargements near one end and oppositely tapered therefrom, a strapinclosing the enlargements and limiting the pivoting of the handles, apivot connecting one handle with the strap, means for normally drawingthe handles together to separate the jaws and wedge means for spreadingthe handles and holding the jaws in clamping engagement with an article,said means com-prising a roller disk arranged with its axis transverseto the line of its movement, said disk being located between the handlesand provided with means for retaining the disk against lateraldisplacement.

2. A Wrench comprising handles adapted for pivotal movement, saidhandles having 5 convex portions pivotally engaged and havinglongitudinal grooves in their inner faces, a spring connecting the freeends of the handles to hold the jaws separated and a circular Wedge diskoperating in the groove to move the jaws together said disk 10 havingits axis transverse to its line of movement.

In testimony whereof, I aifix my signature, in presence of twoWitnesses.
